Hi all,
I discovered and joined this community recently as I was doing some research about this condition over concerns I have over how this might affect my current intimate relationship. I’ve found so much valuable information here and so much kindness and support, even in the prompt replies to my first ever comments, so first and foremost I’d like to thank everyone here again for sharing their experiences, expertise, and care ![]()
I got a lot of reassurance from the information I could already find but I still have some open questions about my specific situation, which I hope someone here could help answer.
A brief overview of my situation:
- Tested positive for HepB antigens and negative for antibodies, 1.5months ago during a standard health screening. Liver function tests all normal.
- Took me by surprise as I’ve been vaccinated since birth in accordance with my country’s national immunization program; however, I’ve long known my mom is my carrier
- My personal history strongly suggests I have been an asymptomatic chronic carrier since birth, although I will only go for follow-up tests 4.5 months later. (Though this is somehow the first time I got a HepB panel so I will never be 100% sure when I was infected–it was not included in my previous health screening, and I was never actively thinking about it despite my family history since I always assumed I had immunity)
- I am relatively young and live a very healthy lifestyle (regular exercise, good diet, zero alcohol)
- Currently in a long-distance intimate relationship. I was physically with my partner for a month before I went for the health screening and tested positive for HPB, and we had a lot of unprotected sex
- Immediately updated my partner about my results after I got them and told him to get tested. His results came back negative for both antigens and antibodies couple of days ago. A relief! I told him to get vaccinated ASAP, and he’s scheduled for his first shot today.
- Buuuut the full series is only complete after 6months, and he will be visiting and we will be physically together again in ~2months time, meaning he will only have managed the second shot by then
This is where I have some open questions that I’m hoping this community can help answer. I’ve asked him to check with his doctor today too but it would be very good to also get some independent validation. Obviously, I want to continue being sexually intimate with him and would love to avoid protection if it’s possible, again for obvious reasons, so:
- Would you recommend him to get tested for his immunity (which I assume is to just run the standard HepB panel which includes the test for antibodies, please correct me if I’m wrong) before he visits so that we can be sure he has responded properly to the vaccine?
- Also, is there a standard level of immunity above which we can say the risk of transmission is really negligible? Like a certain cut-off point for levels of HepB antibodies? And would this generally be reached by the second booster or is just testing for antibodies the best way to find out?
- Would you recommend that I do a HepB viral load test as well before he comes just to be sure my load is low? From what I understand talking to my mom, they don’t recommend viral load tests here until you are actively managing a flare-up, as it’s quite expensive (>$200). I’m not technically due for my follow-up check up until 4.5months later, but even then I don’t think the doctor said to do a viral load test, just liver scan, liver function tests and the standard HepB panel again. So given that I didn’t infect my partner after all the unprotected sex we already had, and let’s say he manages to confirm his immunity after vaccination, do you think a viral load test is still a necessary precaution to take? It’s quite expensive so I’d like to balance utility with the cost, and I am trying to understand what the true utility really is here if we are taking all other sensible precautions already.
Those are my open questions, and then below is a summary of conclusions I got reading the information in this community, that I shared with my partner. Do you think these are reasonable and if there’s anything else I should be communicating with him? (And maybe having a nice summary here might also help others wondering similar things to me)
- Not so good news: even though it won’t be “fully confirmed” until I go for the screening again 6 months later, based on all info I think it’s highly highly likely I’m an asymptomatic carrier with a chronic infection, both based on my family and sexual history, and the fact that most chronic infections happens when one gets infected as a kid, not adult
- Good news: 90% of adults, whether vaccinated or not, who are exposed to HepB will be able to clear the virus without the infection becoming chronic. (Even though the symptoms of an acute infection won’t be fun. But just exposure also doesn’t mean you’ll get an acute infection with symptoms.)
- Good news: female-to-male/bottom-to-top transmission risk is “quite low” (I guess it makes sense) → question to the community: how low is “quite low”, exactly?

- Good news: vaccination is very effective at preventing infection in the vast majority of cases (90-95%), but there is still a small percentage people who don’t develop antibodies and immunity even after vaccination
- Good news: infection usually happens when an infected person’s body fluids with the virus directly enters another person’s blood, like through a scratch of an open wound. So unless you have cuts/sores around your genitals, chances seem quite low. But definitely best to avoid sex when I’m actively bleeding

- Speculative good news: given that you weren’t infected after we had quite a bit of unprotected sex and I’m asymptomatic, and I also generally live healthily, I’m hopeful that my viral load is quite low, too low to even have much risk of transmission whether you’re vaccinated or not, but especially, if you’re vaccinated
It would also be good to know if anyone has any other advice for precautions we could take in our situation! Of course the ultimate fallback is to just use condoms…but would like to avoid that if possible
especially since we are still going to be going long stretches not physically together for awhile until we manage to settle in the same place ![]()
Thanks again for the help! ![]()
